Loving this book so, so hard.
Covers clans' (the 13, plus Caitiff and some antitribu--others are mentioned but more in relation to others, alas none of Saulot's get) beginning stories, histories, some alternate bloodlines and factions, merits/flaws, upper-level disciplines, and combination disciplines.
Honestly, though, I've just been reading it almost like a novel. A lot of insight into the clans and a bit of their correlations between each other and even a little into relations with other supernaturals where it's relevant.
[5 of 5 Stars!]
